Formost American kids, it wouldn't be Halloween without trick-or-treating forcandy;however, that wasn't always the case. When the custom oftrick-or-treating started in the 1930s and early 1940s, children were giveneverything from homemade cookies and pieces of cake to fruit,nuts, coins andtoys. In the 1950s, candy manufacturers began to get in on the act and promotetheir products for Halloween, and as trick-or-treating became more popular,candy was increasingly regarded as an affordable, convenient offering. Itwasn't until the 1970s, though, that wrapped,factory-made candy was viewed asthe only acceptable thing to hand out to all the little ghosts and goblins thatshowed up on people's doorsteps. A key reason for this was safety, as parentsfeared that real-life boogeymen might tamper with goodies that weren'tstore-bought and sealed.
Today,when it comes to Halloween candy, a number of the most popular brands areenduring classics. For example, the first Hershey's Milk Chocolate bar wasproduced in 1900 and Hershey's Kisses made their debut in 1907. Company founderMilton Hershey was a pioneer in the mass-production of milk chocolate andturned what previously had been a luxury item for the well-to-do into somethingaffordable for average Americans. In the early 1900s, he also built an entire town,Hershey, Pennsylvania, around his chocolate factory. In 1917, Harry BumettReese moved to Hershey, where he was a dairyman for the chocolate company andlater worked at its factory.Inspired by Milton Hershey's success, Reese, whoeventually had 16 children, began making candies in his basement. In themid-1920s, he built a factory of his own and produced an assortment of candies,including peanut butter cups, which he invented in 1928 and made with Hershey'schocolate. During World War II, a shortage of ingredients led Reese to pull theplug on his other candies and focus on his most popular producter, peanutbutter cups. In 1963, Hershey acquired the H.B Reese Candy Company.
In 1923,a struggling, Minnesota-born candy maker, Frank Mars, launched the Milky Way bar,which became a best-seller. In 1930, he introduced the Snickers bar, reportedlynamed for his favorite horse, followed in 1932 by the 3 Musketeers bar. Frank'sson Forrest eventually joined the company, only to leave after a falling outwith his father. Forrest Mars relocated to England, where he created the Marsbar in the early 1930s. In 1941, he launched M&Ms. Mars anticipated that WorldWar II would produce a cocoa shortage, so he partnered with Bruce Murrie, sonof a Hershey executive, in order to have access to a sufficient supply ofingredients; the candy's name stands for Mars and Murrie.
Anothercrowd-pleasing Halloween candy, the Kit Kat bar, was first sold in England in1935as a Rowntree's Chocolate Crisp and in 1937 was rechristened the Kit KatChocolate Crisp. The name is said to be derived from a London literary andpolitical group, the Kit-Cat (or Kit Kat) club,established in the late 17thcentury. The group's moniker is thought to be an abbreviation of the name ofthe man who owned the shop where the group originally gathered. Since 1988, thebrand has been owned by Nestle, maker of another perennial trick-or-treatfavorite, the Nestle Crunch bar,which debuted in the late 1930s.
